COMPRESSED-AIR OILER.

Specification of Letters Patent.

Application filed April 8, 1916. Serial No. 89,940.

To all whom it may concern:

Be it known that we, EDWIN E. BAKER and GUY H. SNAVELY, citizens of the United States, residing at \Villows, in the county of Glenn and State of California, have invented certain new and useful Improvements in Compressed-Air Oilers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to hand oilers, and has special reference to a compressed air oiler wherein air may be first pumped before the discharge valve is open, whereby when plunger is provided which will normally remain in a position to retain the discharge valve in a closed position, but which may be actuated for rotating the valve for allowing oil to be discharged from the can under compressed air force.

With these and other objects in view, this inventionconsists of certain novel combinations, constructions, parts as will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a side elevation of the compressed air oiler, as constructed in accordance with this invention.

Fig. 2 is a rear elevation of the compressed air oiler.

Fig. 3 is a central vertical section through the device. v p

Fig. 4 is a section taken on the line -44 of Fig. 3, looking in the direction of the arrow.

Fig. 5 is a fragmentary sectional view through the discharge valve.

Fig. 6 is a top plan view of the plunger used for operating the discharge valve.

Referring to the accompanying drawings by numerals it will be seen that the compressed air oiler comprises a cylindrical can and arrangements of ends so as to 1, having a bottom 2 and a cap 3. The ,bottom 2 and cap 3 are soldered upon the body 1 so as to form a substantially one-piece hollow can which will constitute the reservoir for the compressed air oiler, which may be filled after removing the screw cap 47. Before the cap 3 is positioned upon the upper portions of the body 1, the partition 4 is positioned within the can so as to extend in an inclined plane, as clearly shown in Fig. 3. A curved. tube 5 is also positioned within the can body 1 so as to extend thereabove to be fixedly secured to the inner upper portions of the cap 3. The lower por-' tion of this tube is carried so as to communicats with the opening 6 formed in the partition 4, and is soldered or otherwise secured in position, so as to prevent the passage of oil or air between the lower end of the tube 5 and the inner portions of the opening 6. It will further be noted by re ferring particularly to Figs. 3 and 4 that the partition 4 is provided with an opening adjacent one periphery thereof, so that this opening will be contiguous to the inner portions of the bottom 2.

The pump comprises a hollow casing 8 which is supported at a spaced distance from one side of the can body 1 by means of the supporting bands 9 and 10. These bands 9 and 10 are adapted to be soldered or other wise secured upon the side portions of the can body 1 so as to fixedly retain the casing 8 in its correct position at a spaced distance from the can body as shown clearly in Figs. 1 and 3. These bands 9 and 10 are similarly constructed and are looped at their outer pass about the outer portions of the casing- 8 so as to be suitably secured thereon for fixedly supporting the casing 8.-

This casing 8 is also provided with a cap 11, having an internally threaded rim 12 fitting upon the threaded portion 13 of the casing 8 so as to allow the outer portions of the plunger 14, which is reci roc'ally mounted within the casing 8, to be e ciently gripped by the cap 11 for preventing the escape of air, wardly. The lower portion of the casing 8 is also provided with a base 15 having an internally threaded portion for engaging the lower threaded portion 16 of the casing 8, whereby the base will be efiiciently retained in position. This base 15 is also provided with a port 17 which is ada ted to be intermittently closed by means 0 as the plunger is moved downvalve 18. The valve casing 19 is soldered or otherwise secured upon the outer portions 1 of the can body 1, so as to communicate w1th sitioned within this valve casing seen that as the plunger 14 is moved up wardly air will be sucked into the pump casing 8, since the suction will leave the flap valve 18 open, at which time the ball valve p 23 will engage the valve seat 24. As the plunger 14 is moved downwardly, however, the flap valve 18 will swing to close the port 17, whereby the air Within the pump casing 8 will pass the ball valve 23 past the spring seat 24 whereby the air may be passed through the opening 20 and into the can body.

The gate or discharge valve 25 is carried by the secondary valve casing 26 I fixedly mounted upon the upper portion of the cap 3 of the can body 1. Thls secondary valve casing is provided with a central vertical passage 27 communicating with the tube 5, as shown clearly in Fig. 3. The elongated support 28 is adapted to be mounted upon the upper ortions of the secondary valve casing 26 y wedging over the neck 29 thereof, as shown in Fig.

3. This gate valve I or discharge valve 25 is provided with a sliding arm 34 in threaded outer end 30 upon which the nut 31 is adapted to be threaded for holding the valve which tapers toward its threadedend, as shown clearly in'Fig. 5, in its correct position upon ing 26. An operatlng pin 32 extends slidably through the opposite end of the valve 25, as shown clearly in Fig. 5, and depends so as to fit upon the reduced portion 33 of the sliding arm 34. It will be noted that the lower end of the pin 32 is bifurcated, as shown at 35, so as to fit portion 33 of the sliding arm 34, at which time the pin 36 may e passed through the bifurcated end and. through the reduced portion 33 for positively in engagement with th sliding arm 34, Frames 37 and 38 are ca ried upon the upper portions of the cap 3 for retaining the its correct position. The frame 37 has a fiat top from which the side portions 39 depend so that this frame will-- be in construction a substantially inverted U-shaped conformation. The side portions 39 have thelips 40 bent to extend in a substantially arch plane, conforming in contour and fitting snugly upon theupper portions ofthe cap 3, and as these lips may be through the passage 21 urging through the the secondary valve casupon the reduced holding the pin' soldered or otherwise suitably secured, the frame will be retained in a set position. The frame 38 is constructed so as to provide a verticalside 41' carrying the depending side 42 from. which extends at an angle of approximately 45 the leg 43, and upon the lower end of the side 41 and leg 43 are the lips 44, which are suitably secured upon the cap rect position. The sliding arm 34 is s'lidably mountedupon these frames, as .shown clearly in Fig. normally urged in one direction by means 3 for retaining the frame 38 in its-cor- 1, and-this sliding arm 34'is of the coiled'spring 45,. which bears at one end upon the depending portion 42 of the frame 38 and at the opposite end upon the in 45 extending through the sliding arm 34. ,The' sliding arm 34 is also provided tion 46 is released. I

When this device is in operation the screw 7 cap 47 may first the oil may be the can body. .1 e oil openin be removed, at which time 7 formed in the part1 tion 4 and wardly into the tube 5 to the same level as the oil within the can body 1. The screw cap 47 may then be positioned upon the body '1. At this time the tension of the spring 45 will urge the shifting arm 34 in one direction for retaining the valve 25 in a closed position as shown in Fig. 3. When it is desired to force oil from .the interior of the can body 1, it is first necessary to provide the interior of the can body with air. This is accomplished by the reciprocating of the plunger 14. As the air is sucked through the port 17 and "into the valye casing 8 the flap valve will be retalned in an open position. Upon the downward movement of the plunger 14, however, the flap valve will fall to a closed position, valve 23 to compress the spring and will then pass through the opening 20 into the interior of the can body 1. The compressed air will then pass upwardly into the upper portions of the can body 1 and the cap 3. This action of the pump may be continued until a very high pressure is obtained in the upper portions of the can body 1. At this time the can will be ready for discharging the oil, and this action may be accomplished.

the 1 by gripping the handle 8 and pullingi sliding arm 34 away from the can bc y 1.

As this sliding arm 1s pulled, it will, of

course, swing the pin 32, which will in turn rotate the discharge or gate valve 25, there by openin the passage 27 through the secondary veilve casin 26. The force of the compressed air within the upper portions of oured into the interior of- Wlll pass'downwardly f Wlll then pass around and up-- with acurved grip portion 46 by means of I while the air will force the ball that the can may be held in can win an inverted upon the bottom the body 1 and the inner portions of the cap 3 will be of such-strength as to force the oil within the body 1 downwardly. This action will cause the oil to pass through the opening 7, beneath the partition 4, and then upwardly through the tube 5, the passage 27 and through the spout 28. It will be seen any desired pocasing 8, which the compressed of course, be at sit-ion by gripping the valve will constitute a handle for air oiler. The spout may,

It will, of course, be noted that the side edge or periphery of the partition the inner surface of the. can body throughout its entire length. This partition bears adjacent the lower end of the can body, whereby one of the openings in the, partition willbe carried in very close proximity to the bottom. Since the partition slants away from the bottom of the can body, the portion of the partition adjacent the remainin opening will be spaced at a considerable distance from-the bottom. This necessarily makes the partition elongated. The tube 5 engages the partition adjacent the openin farthest from the bottom of the can bo y. The partition d is held against slipping or turning, and itis tion at all times.

What is claimed is:

In a compressed air oiler of the class described, the combination of a can body having a flat bottom, a slanting partition carried within said can body, said partition having openings formed therein adjacent its periphery and at opposite portions of said partition, a portion of said partition bearing upon said bottom adjacent the lOWer' portion of said can body, one of said openings being carried at a oint in close proximity to said bottom, t e portion of said partitionadjacent the remaining opening bearing upon said can body at a distance. from said bottom,

the periphery of partition engaging throughout its entlre length the inner portion of said can body, a tube carried by said can body and communicating with the inner surface of said partition by projecting into the opening carried farthest from said bottom, said inclined, elongated partition engaging both said bottomand said tube, whereby said partition will be positively held in a'set position within said can body, I

and means for forcing air into said can body above said partition.

In testimony whereof we hereunto afiix our signatures.
